The environment we live in is facing many serious problems. We need to be aware of these problems so that we can find ways to protect nature.
Global warming is the rise in the average temperature of the earth's atmosphere. It is one of the biggest issues facing humans today. It can have serious consequences such as rising sea levels, polar ice melting. and extreme weather events like floods or heatwaves.
Another environmental problem is the cutting and clearing of natural forests. The loss of forests can have a negative impact on the environment. It can damage the natural habitats of many animals and put wildlife in danger. It can also destroy the natural soil and lead to climate change.
Air pollution is also a serious problem. It is mainly caused by waste gases that come out of vehicles, machines, or factories. When these harmful gases combine with the water in the air, they come down as rain or snow, which can damage all forms of life. In addition, this problem leads to global warming and climate change. It is also a major cause of respiratory diseases or even lung cancer.
Around the world, the number of endangered animals is rising. Many of them disappear because of pollution and climate change. In addition, humans illegally hunt and kill animals., and catch too much fish at once. This is upsetting the natural balance of ecosystems, which can be harmful to all living and non-living things
