IMPACT OF HUMAN ACTIVITIES IN AN ECOSYSTEM

This is the cultivation of a single crop in large areas. Vast tracts of land are converted to rice farms, sugar farms, and coconut farms.

• Water pollution

• Monoculture

• insecticide

• antibiotics

Farmers spray these chemicals to kill insect pests and weeds.

• Water pollution

• Monoculture

• insecticide

• antibiotics

Continuous and uncontrolled use of ______________ may increase soil acidity, thus destroying soil structure.

• Water pollution

• Chemical fertilizer

• insecticide

• antibiotics

It is clearing the Earth's forests on a large scale worldwide and resulting in many land damages. One of the causes of deforestation is to clear land for pasture or crops.

• Deforestation

• Chemical fertilize

• insecticide

• antibiotics

Is the use of plastic mulch in agriculture. Farmers use plastic sheets as mulch to cover 50-70% of the soil and allow them to use drip irrigation systems to have better control over soil nutrients and moisture.

• Deforestation

• chemical fertilizer

• plasticulture

• Antibiotics

A huge amount of agricultural territory is used primarily as pasture for cattle and other livestock.

• Grazing

• deforestation

• pesticide

• antibiotics

Antimicrobial resistant bacteria can move from farms to humans through food and airborne dust.

• Grazing

• deforestation

• pesticide

• antibiotics

Resulting from conventional agricultural practices is wide-reaching, affecting both surface and groundwater sources, in agricultural communities and those located downstream.

• Water pollution

• Monoculture

Influences social and environmental determinants of health, including air and water quality and food security. Agriculture and related activities contribute significantly to climate change through greenhouse gas (GHG) emissions.

• Water pollution

• Monoculture

• climate change

• antibiotics

The gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem such as a lake.

• Water pollution

• Monoculture

• climate change
