Human activities have made big changes to our natural world. Here are some of the ways this has happened:
Cutting Down Forests (Deforestation): Every year, we lose over 13 million hectares of forest. This loss makes it hard for plants and animals to have homes and also affects how much carbon is stored in the environment.
Growing Cities (Urbanization): By the year 2050, about 68% of people around the world are expected to live in cities. This growth breaks up natural habitats, which is not good for wildlife.
Farming Expansion (Agricultural Expansion): Farming takes up around 38% of the Earth's land. This affects the variety of plants and animals and can also harm our water supplies.
New Species (Invasive Species): When non-native species are brought into new areas, they can crowd out 48% of the native species. This causes many local plants and animals to decline.
All these changes are harmful and result in fewer kinds of living things (biodiversity) and make ecosystems less stable.
