Walnuts are good for everyone, but their only drawback is that they need to be peeled. Some of them are so difficult to peel that often half of the kernels have to be thrown away along with the shell. There is one little trick that saves energy, nerves and time. It turns out that the nuts need to be boiled a little. So, if peeling walnuts takes a lot of time, you need to boil them in boiling water.

How to boil walnuts

1. First you need to bring to a boil the volume of water that should correspond to the number of nuts that you decided to finally peel from the shell.

Anacondas, which live in the warm tropical climate of South America, are the largest snakes in the world and are among the most dangerous. Although they are not venomous reptiles, they can wrap their bodies around large prey, strangle it and eat it.

Anyone who encounters an anaconda is scared to death, but a local fisherman in Brazil was very surprised. So much so that he wrestled with the reptile, laughing and holding it by its huge tail.

Footage posted on Reddit shows the fisherman fighting the anaconda. The man grabs it and begins to swing it wildly from side to side, while the animal tries to defend itself as best it can and attacks to continue its journey downstream.

The incident reached the ears of Brazilian authorities, who did not hesitate to fine the fisherman and his companions for disturbing the anaconda.

The massive use of plastic products has led to the accumulation of gigantic amounts of plastic waste, which not only pollutes the environment, but also has a destructive effect on ecosystems. In search of a solution to this problem, new technologies for recycling plastic waste are increasingly being developed that can not only reduce their amount, but also give plastic products a second life. The plastic revolution, or the transition to efficient and environmentally friendly management of plastic waste, is becoming an important part of modern sustainable development.

One of the most popular technologies for recycling plastic waste is mechanical recycling, which involves the process of sorting, crushing and melting plastic to obtain secondary raw materials. These methods allow used plastic products to be converted into new products, such as packaging, plastic containers, and various building materials. Mechanical recycling is a relatively affordable and widely used method, but it has its limitations. For example, when plastic is processed mechanically, its quality may decrease, and it is also important to consider that not all types of plastic can be recycled in this way.

One of the most promising technologies for recycling plastics is chemical recycling. Unlike mechanical recycling, chemical recycling breaks down the molecular structure of plastics and converts them into new chemicals or products that can be used in a wide range of industries. One such method is pyrolysis, which involves the decomposition of plastic at high temperatures in the absence of oxygen. As a result of pyrolysis, the plastic is converted into liquid hydrocarbons that can be used as fuel, or into gaseous products that can be processed into various chemical compounds. Another technology is hydrolysis, which breaks down plastics using water and chemicals, turning them into monomers that can be used to make new plastic.

Biological recycling of plastics is another innovative approach that could change the future of the plastics industry. Research shows that certain microorganisms can break down plastics, opening up new horizons for the sustainable management of plastic waste. For example, scientists have discovered that some bacteria can break down polyethylene, one of the most common types of plastic. This process, called biodegradation, could be an important step in the fight against plastic pollution. However, the technology is still in its development stage and requires further research before it can be widely used.

Over the past few decades, humanity has realized that the destruction of forests has serious environmental and climate consequences that can have catastrophic consequences for all life on Earth. It is important to understand why forests are so important for the climate and what could happen if we do not pay due attention to the protection of these ecosystems.
Forests play a key role in regulating the planet’s carbon balance. One of the key functions of trees is to absorb carbon dioxide from the atmosphere. During photosynthesis, plants use carbon dioxide (CO₂) and sunlight to create organic matter and release oxygen. This process helps reduce the amount of carbon dioxide in the atmosphere, which in turn helps reduce the greenhouse effect, which is one of the main causes of global warming. According to scientific research, forests absorb about 30% of the carbon dioxide released into the atmosphere as a result of human activity. This means that protecting and restoring forests has a direct impact on the fight against climate change. In addition, forests contribute to increased air humidity, which helps regulate climatic conditions in regions.

Trees absorb water from the soil and then evaporate it through their leaves through the processes of transpiration and evaporation. This promotes the formation of clouds and precipitation, thereby improving climatic conditions in the region. Forests also prevent sandstorms and dehydration by retaining moisture in the soil and maintaining a stable microclimate. In places where forests are cut down or degraded, this process is disrupted, leading to increased drought, reduced agricultural yields and worsening human living conditions.

In the context of global environmental problems and the depletion of traditional resources such as oil and coal, the development and use of alternative energy sources is becoming a priority for many countries and scientific institutions. These sources can significantly reduce dependence on fossil fuels, and also reduce harmful emissions into the atmosphere that contribute to climate change.

One of the most popular and affordable alternative energy sources is solar energy. Solar panels, which can be installed on roofs or in large solar farms, are already actively used around the world. Solar energy is practically waste-free and clean, since the process of energy production occurs without carbon dioxide emissions. Solar panels use the energy from the sun’s rays to generate electricity, making them a reliable source of renewable energy. However, one of the main limitations of solar panels is their dependence on weather conditions. The efficiency of solar panels decreases on cloudy and rainy days and at night. Wind energy is another common and promising energy source that is actively used in different parts of the world. Wind energy works by converting the kinetic energy of the wind into electrical energy using wind turbines. This energy source is becoming increasingly common, especially in regions with constantly strong winds. Wind turbines can be installed on land as well as in coastal areas where the wind is most stable and strong. However, wind, like the sun, is not a constant source of energy, which limits its use in regions where windless days are common. Nevertheless, the use of wind energy is constantly increasing due to its cleanliness and cost-effectiveness. Hydrogen energy is also considered an important source of the future. Hydrogen is the lightest element in the universe and its use as a fuel is environmentally friendly, as only water is released when hydrogen burns. Hydrogen fuel cell technology converts hydrogen into electricity, a process that could become an important part of the fight against global climate change.

Hydrogen can be used not only in the energy sector, but also in the transport sector, where hydrogen cars are an environmentally friendly alternative to traditional gasoline and diesel cars. However, the main obstacle to the widespread adoption of hydrogen energy is the high cost of the technology and the need to create an infrastructure for the production and storage of hydrogen. Geothermal energy is another way of obtaining energy from natural sources. Geothermal power plants use heat stored deep in the Earth to generate electricity. This can be either heat released from magmatic and volcanic areas, or heat located at a shallower depth. Geothermal energy is a stable and efficient source, because the temperature inside the Earth does not depend on weather conditions or the season.

One way to contribute to the well-being of the planet’s environment is to create a zero-waste home. Every year, people are becoming more aware of the importance of minimizing household waste and are beginning to use various methods to reduce its amount.
The main concept here is “Zero Waste” – a philosophy of living without waste, which includes the rejection of disposable items and products, as well as their recycling and reuse. The emphasis is on reducing waste at all stages of the life cycle, from the purchase of products to their disposal. The transition to this lifestyle not only helps to reduce the amount of waste, but also reduces your carbon footprint and reduces pollution.
Step 1: Minimize Packaging
The first and most important step in moving towards a zero-waste home is to eliminate single-use packaging. This can include plastic wrap, cardboard boxes, polyethylene bags, and more. When people buy packaged goods, they often don’t think about how much of it can be recycled and how much ends up in landfill, which is damaging to the environment. But every year, manufacturers are starting to pay more attention to packaging recycling and the use of biodegradable materials.
An easy way to reduce packaging is to buy products without packaging or with minimal packaging. In large cities, there are already stores where you can buy products without packaging: from flour and cereals to soap and shampoo. In such stores, customers can use reusable containers for grocery shopping and bring their own bags and packages to avoid using plastic bags.
If such stores are not available, you can use reusable containers, cans, and grocery bags, which will significantly reduce the amount of plastic packaging.
Step 2: Use reusable products
Plastic and disposable items such as dishes, cutlery, cups, and plates are becoming one of the main sources of waste in households. Their use contributes to a large amount of waste that usually ends up in landfills. However, you can easily get rid of this problem by replacing disposable products with reusable ones. Glass and metal containers, bottles, pots, and other household items will last much longer and can be recycled or reused after use.
It is especially important to pay attention to the rejection of single-use plastic bottles and beverage containers. You can use thermoses and reusable water bottles instead. These simple steps will not only help you minimize waste, but also help you reduce your overall plastic consumption.

Globalization and urbanization are becoming factors that have a direct impact on the future of cities. Sustainable development is not just a trend, but a necessity aimed at creating cities that can not only meet the needs of the current population, but also provide a comfortable life for future generations. How are megacities moving towards sustainability and what does this mean for the future of urban life?1. Sustainability as a foundation
Sustainable urban development is a concept that encompasses a balance between economic, social, and environmental aspects. The main goal is to create an urban environment where resources are used efficiently, pollution is minimized, and the quality of life is improved for all segments of the population. The most important principle is not only to reduce the negative impact on nature, but also to ensure equal access to services and opportunities for all residents.
More and more cities around the world are beginning to implement sustainable development strategies, focusing on reducing their carbon footprint, efficient use of water and energy, the development of public transport and green spaces, and the use of environmentally friendly materials in construction.
2. Innovation in architecture and construction
New technologies and innovative approaches can significantly change the appearance of cities. One of the most striking examples of sustainable construction is the use of environmentally friendly materials, such as recycled plastic panels, low-carbon concrete and green roofs, which help reduce temperatures in cities and improve the energy efficiency of buildings.
Modern architects are actively implementing the principles of “smart” construction, which includes the installation of solar panels, rainwater harvesting systems and “smart” energy management systems. This allows us to significantly reduce the consumption of natural resources and make buildings more energy efficient.
Green buildings are becoming not only a trend, but also a mandatory norm. For example, some countries have already introduced strict environmental standards that require new residential complexes and office buildings to meet energy efficiency standards and use environmentally friendly materials.
