What determines what life exists in a biome?
Why do different biomes have different types of plants and animals?
Over the past several decades, increasing human activity has rapidly destroyed or polluted many ecological habitats throughout the world. It is important to preserve all types of biomes as each houses many unique forms of life.

May 22, 2020 · Biodiversity is critically important to human health, economies and livelihoods. Humans have caused the loss of 83% of all wild animals and half of all plants. To mark the International Day for Biodiversity, here are five reasons why biodiversity matters to humans – and why we need to protect it.

Earth’s biosphere consists of five main types of biomes: aquatic, grassland, forest, desert, and tundra. These biomes can be further divided according to location, elevation, or other definitions. Biomes are generally defined by the types of vegetation, soil, climate, and wildlife within them. Note that a biome is different from an ecosystem. A bio...
Biomes can be affected by changes within the Earth system at both long and short timescales. The primary biome present in an area can change over time as the climate changes. Ten thousand years ago, parts of North Africa were green, lush landscapes with abundant trees and flowing rivers. Today, that region is part of the Sahara Desert, the world's ...
Over time, many of Earth's biomes have been impacted by human activity, and these changes began to happen almost as soon as humans were around. For instance, hunting by early humans is thought to have contributed to the extinction of some megafauna, and the controlled burning of forests dramatically altered landscapes as long as 12,000 years ago. I...
Agriculture is a human activity having significant impacts across biomes as well as the whole Earth system. The entire food system — from production to consumption — accounts for about 25% of total greenhouse gas emissions into the atmosphere. Agricultural production has advanced to feed the world’s growing population, which quadrupled in size over...
Wildfire is another factor affecting Earth’s biomes, particularly the planet’s forests. Wildfires are a part of nature, but recent years have seen more fires, as well as larger fires, than in the past. The number and size of wildfires are increasing in part due to warmer, drier conditions that lengthen the fire season. Instead of fires typically oc...
Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat.
How do humans affect biodiversity? Humanity impacts the planet's biodiversity in multiple ways, both deliberate and accidental. The biggest threat to biodiversity to date has been the way humans have reshaped natural habitats to make way for farmland, or to obtain natural resources, but as climate change worsens it will have a growing impact on ...
Oct 19, 2023 · An ecosystem is the interaction of living and non-living things in an environment. A biome is a specific geographic area notable for the species living there. A biome can be made up of many ecosystems. For example, an aquatic biome can contain ecosystems such as coral reefs and kelp forests.
Apr 10, 2019 · Biomes with low precipitation, extreme temperatures, short growing seasons, and poor soil have low biodiversity -- fewer kinds or amounts of plants and animals -- due to less than ideal growing conditions and harsh, extreme environments.
