Human activities have a big impact on how populations of animals and plants change over time and how ecosystems grow and change. Here are some important ways these activities affect nature:
Habitat Destruction: When people create cities and cut down forests, we lose a lot of places where animals and plants can live. In fact, around the world, we have lost about 50% of these habitats. This makes it really hard for many species to survive.
Resource Exploitation: We often take too much from nature, like overfishing and hunting. For example, between 1970 and 2015, the number of marine fish has dropped by 50%. This shows how our actions can reduce animal populations.
Pollution: Chemicals from our activities can harm the environment. Since 1980, pollution has caused a 50% drop in the number of amphibians, like frogs and salamanders. This pollution affects their ability to reproduce and survive.
Invasive Species: Sometimes, we accidentally bring in non-native species that do not belong in certain areas. These invasive species can upset the balance of local ecosystems and are responsible for 40% of the global extinction events.
All these factors make it harder for animal and plant populations to thrive and can change how ecosystems develop. They can slow down recovery and reduce the variety of life we see in nature.
