Human activities have a big impact on nature and how animal and plant populations grow and shrink. Here are some ways this happens:
Habitat Destruction: When we cut down forests, build cities, or farm land, we destroy homes for many plants and animals. Right now, we are losing about 10 million hectares of forest every year. This loss harms the variety of life and affects how many animals and plants can survive.
Pollution: Harmful chemicals and trash can hurt the environment. Research shows that pollution can cause a drop in certain animal populations by up to 90%. That's a huge number!
Overexploitation: Catching too many fish or hunting too many animals can lead to serious problems. The United Nations says that around 34% of fish around the world are caught too much. This overfishing can really harm ocean life.
Invasive Species: Sometimes, people bring in new plants or animals that do not belong in an area. These invasive species can take over and push out the local plants and animals. A good example is the cane toad in Australia, which has led to a drop of over 70% in some local frog populations.
Climate Change: Climate change caused by humans changes the environment and where different species live. Studies predict that if the world warms by just 2°C, we could lose about 30% of all species.
Understanding these issues is really important if we want to take care of our ecosystems in a smart way.
