Identify and explain two problems that modern agriculture has caused for the environment.

Two problems that today's agriculture has caused is soil erosion and a decrease in biodiversity in the environment. This is especially due to mono-cropping of large tracks of land.   Lands cleared for agriculture almost immediately begin to erode away, usually by wind or running water. Due to monocropping, the reduced variety of plants on the environment causes a consequent deduction in a variety of animals in the region such as pollinators due to the availability of only one type of plant for pollination.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

this is an example of a symbiotic association of a protozoan with its mode of association.
