Human actions have a big impact on ecosystems. Here are some ways we affect the environment:
Habitat Destruction: Every year, about 1.2 million square kilometers of forests are lost. This makes it hard for animals and plants to find homes and hurt the variety of life.
Pollution: More than 80% of the pollution in the ocean comes from activities on land. This hurts marine life and the health of the species living in the water.
Resource Exploitation: Overfishing has caused some fish populations to drop by 90% since 1950. This changes the food chain and how different species interact with each other.
Climate Change: Human activities have caused the average global temperature to rise by about 1.1°C. This change affects where animals and plants can live and alters the boundaries of their ecosystems.
Invasive Species: When new species are introduced to an area, they can take over and push out native species. Invasive species have been linked to about 40% of extinctions in the last 500 years.
All of these activities change important parts of ecosystems, like the variety of life, how species interact, and how nutrients move through the environment.
