Explain why many sustainable fishing and forestry practice depend on the actions of consumers like you.

Answers

Answer:

The reason why many sustainable fishing and forestry practice depend on the actions of consumers like me is:

  • The offer is aimed at satisfying the demand for these products.

Explanation:

Sustainable fishing and  forestry are based on allowing future generations to access the same products that we currently have, for this reason, a sustainable fishing practice can be waiting for fish to reproduce, in order to not to overexploit them and thus to extinguish them, however, as mentioned in the answer, the offer is aimed at satisfying the demand, therefore, if consumers like me demand sea products even though they are not in the breeding season or without providing the time for the ecosystem to recover the extracted products, the supply will be forced to supply the demand despite the extinction of a species; The same applies to sustainable forestry, if they carry out reforestation work on wood products in proportions 10-1 (10 plants planted for each tree cut) or higher, but the consumer does not provide the prudent time to obtain wood products again, the indiscriminate felling in order to supply the product required by the consumer.

Answer:

Find explanation below.

Explanation:

Sustainable fishing and forestry practice are measures taken t ensure that the fishes and forests are preserved for future generations. Continuous lumbering and fishing can result to a depletion of these resources and in the worst scenario, their extinction. So it lies on both the fishers or lumberers and consumers to take preventive measures. As consumers of these resources we can help in solving these challenges by;

1.  Limiting our consumption of these resources. We can seek alternatives to them as the case may be.

2. Secondly we should take our time to learn about these natural life and the dangers they face. This would help us in choosing sources that adhere to conservative practices.

Answers

The following statements is FALSE :

a. Dry farming methods replaced the need for windmills.

Explanation:

  • Dry farming, also called Dryland Farming, the cultivation of crops without irrigation in regions of limited moisture, typically less than 20 inchesof precipitation annually. Moisture control during crop growing consists largely of destruction of weeds and prevention of runoff.
  • The dry farming method was still in use when windmills were established in West Texas
  • Dry farming works to conserve soil moisture during long dry periods primarily through a system of tillage, surface protection, and the use of drought-resistant varieties.
  • Dry farming is not a yield maximization strategy; rather it allows nature to dictate the true sustainability of agricultural production in a region.
  • Dry farming's purpose was to conserve limited moisture during dry weather by reducing or even eliminating runoff and evaporation, thereby increasing soil absorption and retention of moisture.
