Agricultural Practices
Farms use pesticides. These chemicals kill pests but harm other animals. Pesticides can seep into groundwater. This makes drinking water unsafe. Farms also use fertilizers. Excess fertilizers run off into rivers. This causes algae blooms. Algae blooms reduce oxygen in water. Fish and other aquatic life die.
- Pesticides: Harmful to animals
- Groundwater contamination: Unsafe drinking water
- Fertilizers: Cause algae blooms
- Algae blooms: Reduce oxygen in water
Impact On Ecosystems
Environmental contamination has severe effects on ecosystems. It disrupts natural processes and harms living organisms. This section explores the impact of contamination on marine life and soil health.
Marine Life
Contaminants like plastic waste, oil spills, and chemical runoff affect marine life. Fish, turtles, and seabirds often mistake plastic for food. This can lead to injury or death.
Oil spills cause devastating harm. They coat the feathers of birds and the gills of fish. This makes it hard for them to breathe and move. Chemicals like pesticides and heavy metals enter oceans through runoff. These substances poison marine animals and disrupt their reproduction.
| Contaminant | Impact |
|---|---|
| Plastic | Ingestion and entanglement |
| Oil | Coats feathers and gills |
| Chemicals | Poisoning and reproductive issues |
Soil Health
Soil contamination affects plants, animals, and humans. Harmful substances like pesticides, heavy metals, and industrial waste degrade soil quality. Plants absorb these toxins through their roots.
Contaminated soil reduces crop yield and quality. It makes food unsafe to eat. It also harms animals that rely on plants for food. Soil contamination can cause loss of biodiversity. Many organisms in the soil help decompose organic matter and recycle nutrients. Contamination kills these beneficial organisms, leading to poor soil health.
The table below shows common soil contaminants and their effects:
| Contaminant | Effect on Soil |
|---|---|
