Extinction of Species

Extinction of SpeciesPollutants harmful to aquatic and terrestrial biota. Different types of animals were poisoned and then die. Various species of animals that do not have the same immunity. There are sensitive, some are resistant. Young animals, animals that larvae are sensitive to contaminants. There are animals that can adapt so resistant to pollutants, some are not. Although animals adapt, to know that the level of animal adaptation has its limits. When the limit is exceeded, the animal will die.2. Blasting HamaThe use of insecticides can also be deadly predators. Because the predator species, then. insect pests will flourish without restraint. Spraying with insecticides may also result in some insect species become resistant (resistant). To combat it, required a higher dose than usual. As a result, pollution will increase.

3. Environmental Balance DisordersThe extinction of certain species can alter the pattern of interactions in an ecosystem. Food chains, food webs, and energy flow changes. As a result, the balance of disturbed environments. Recycled materials and recycle biochemical disturbed.4. Declining Soil FertilityThe use of insecticides can kill soil fauna. This leads to decreased soil fertility. The use of fertilizer can lead to persistent soil acidification. It also can reduce soil fertility. To overcome this,Should fertilization with manure or compost, planting systems criss-cross (intercropping), and rotation of crops. Crop rotation means planting different crops alternately in the same land.5. Toxicity and DiseasePeople who eat vegetables, fish, and contaminated food can be poisoned. Poisoning, people can suffer liver damage, kidney cancer, damage the nervous system, causing defects in the offspring even death.6. Biological concentrationPollutants entering the environment through food chains and food webs. Toxic materials are dumped into the water can seep into the body of algae. Furthermore, these algae are eaten by tiny shrimp shrimp eaten by fish. If the fish are caught and then eaten by humans, pollutants will enter into the human body.The process of elevated levels of pollutants through the living body are known as biological concentration (in English known as biomagnification).
