What is the biggest threat of cogongrass?
Cogongrass is a growing threat as it continues its rapid spread across the Southeast, reducing forest and pasture productivity, destroying wildlife habitat, impacting rights of ways and presenting an extreme fire hazard.
What determines where a population can live?
Answer: Biotic and abiotic factors both determine that a population can live or not in a particular place. Abiotic factors include air, water, soil, minerals, temperature et cetera. The basic needs of any living organism include air, water, food and shelter which can not be fulfilled without these abiotic factors.
Can one overshoot the carrying capacity?
Overshoot: When a population surpasses its carrying capacity it enters a condition known as overshoot. Because carrying capacity is defined as the maximum population that an environment can maintain indefinitely, overshoot must by definition be temporary. Populations always decline to (or below) the carrying capacity.
What are the causes of rapid population growth?
These are the leading causes:
- Poverty. Poverty is believed to be the leading cause of overpopulation.
- Poor Contraceptive Use.
- Child Labor.
- Reduced Mortality Rates.
- Fertility Treatment.
- Immigration.
How does rapid population growth affect the environment?
Population growth is the increase in the number of people living in a particular area. Since populations can grow exponentially, resource depletion can occur rapidly, leading to specific environmental concerns such as global warming, deforestation and decreasing biodiversity.
What are the causes and effects of rapid population growth?
Overpopulation is caused by a number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which result in overpopulation. A direct result of this has been the increased lifespan and the growth of the population.
How will population growth affect food security?
The Population Institute estimates that a 70 per cent increase in food production will also have to take into account increases in energy prices, as well as factors such as the groundwater depletion, the loss of farmland to urbanization, and potential flooding and droughts caused by climate change.
What role does technology play in ensuring there is food security?
Technology can support improved economic growth and social well-being; effective harvest and post-harvest practices to minimize food loss; effective storage and conservation practices to increase the value of harvested products; identification of high value added products to improve economic gains for processors and …
What is the impact of rapid population growth on food supply and natural resources?
Overpopulation resulted in land resource scarcity, fragmentation of farm plots, and ecological degradation such as increasing emissions, soil erosion, deforestation, and the overuse of natural resources. Producing adequate food for a rapidly growing population is a prime challenge for development.
What is the relationship between agriculture and population growth?
These environmental conditions are conducive to agriculture (11), which may have increased food productivity, thus accelerating population growth. Accelerated population growth associated with agriculture is sometimes referred to as the Agricultural or Neolithic Demographic Transition (12).
What will agriculture be like in the future?
Future agriculture will use sophisticated technologies such as robots, temperature and moisture sensors, aerial images, and GPS technology. These advanced devices and precision agriculture and robotic systems will allow farms to be more profitable, efficient, safe, and environmentally friendly.
