#148 The Human Influences On The Ecosystem

The usage of modern engineering resulted inward increased nutrient production.

• Increasing usage of pesticides, fertilizers together with herbicides  à ↑ levels of nutrients inward the soil, kill insect pests, kill weeds à ↑ crop yields.

• Use of modern machinery (tractors, combined harvesters) à grapple province together with crop to a greater extent than efficiently.

• Artificial selection to attain varieties of plants suited to item climates together with reason types, together with breeds of creature for specific purposes (optimum meat, milk, wool production).

• Use of yeast and bacteria inward the large-scale production of breads, beer together with wine, yoghurt together with cheese. Single-cell poly peptide together with fungi are used to attain meat substitutes.

• Use of medicines such every bit antibiotics, hormones together with artificial insemination techniques inward intensive animal rearing.

• Use of plant hormones inward found growing together with fruit production.

• Use of genetic engineering together with cloning techniques to attain organisms to attain hormones…

• Development of systems to H2O plants inward greenhouses automatically together with to grow plants inward nutrient solutions (hydroponics).

• Use of satellites to monitor crop development, uncovering crop diseases together with assess the necessitate for additional fertilizer.

• Development of intensive farming together with automated feeding mechanisms.
