Soil pollution has significant impacts on food security, human health, and the environment:

Food Security: Soil pollution reduces crop yields and makes crops unsafe for consumption due to toxic contaminants. This jeopardizes food availability and quality.
Human Health: Contaminated soil can lead to health issues through direct exposure or indirectly via contaminated food and water. It can also contribute to the spread of antimicrobial-resistant bacteria.
Environmental Impact: Pollutants harm soil biodiversity, affecting microorganisms and larger soil-dwelling organisms. This disrupts ecosystems and reduces soil fertility.

A biome is a large ecological area on the Earth’s surface, with flora and fauna (plants and animals) adapting to their environment. Biomes are defined by factors such as climate, soil, and the types of organisms that live there.

Here are some major biomes of the world and their characteristics:

1. Tropical Rainforest:
   • Climate: Warm and wet year-round.
   • Vegetation: Dense, multi-layered forests with a high diversity of plant species.
   • Wildlife: Rich in biodiversity, including insects, birds, mammals, and reptiles.
2. Desert:
   • Climate: Very dry with extreme temperature variations between day and night.
   • Vegetation: Sparse, with drought-resistant plants like cacti.
   • Wildlife: Adapted to arid conditions, including reptiles, small mammals, and insects.
3. Grassland:
   • Climate: Moderate rainfall, with hot summers and cold winters.
   • Vegetation: Dominated by grasses, with few trees or shrubs.
   • Wildlife: Large herbivores like bison and antelope, and predators like lions and wolves.
4. Tundra:
   • Climate: Cold and dry, with short summers and long, harsh winters.
   • Vegetation: Low-growing plants like mosses, lichens, and small shrubs.
   • Wildlife: Adapted to cold, including caribou, arctic foxes, and migratory birds.
