What are pesticides?
Pesticides are substances used to kill, repel, or control pests.
How should animal waste be properly disposed of?
Composting, incineration, rendering, or anaerobic digestion.
What is the difference between point source and non-point source pollution?
Point source pollution originates from a single, identifiable source like a pipe or factory, while nonpoint source pollution comes from multiple, diffuse sources like runoff from agricultural lands or urban area
What percentage of the world’s water is actually fresh and accessible?
While 97.5% of the Earth's water is saltwater, only about 2.5% is freshwater, and of that, less than 1% is readily accessible for human use.
What is a water footprint?
A water footprint measures the total volume of freshwater used, either directly or indirectly, to produce goods and services consumed by an individual, community, or business, including water used for production and pollution
What are herbicides?
Herbicides are chemicals, also known as weedkillers, used to control or eliminate unwanted plants, including weeds, in agricultural and non-agricultural settings.
For the next four questions answer this,
Why is animal waste such a big problem in terms of: nutrient pollution
Animal waste is a significant source of nutrient pollution because it contains high levels of nitrogen and phosphorus.
Why is nonpoint source pollution harder to identify?
Nonpoint source pollution is harder to identify and control because it originates from numerous, diffuse sources, making it difficult to pinpoint the exact origin and responsible parties
What percent of the world’s water is freshwater
3%
Name 2 ways we can directly decrease our water footprint.
All answer will be ok.
What are fertilizers?
Fertilizers are substances added to soil to provide plants with essential nutrients, like nitrogen, phosphorus, and potassium, to promote growth and increase yields.
Why is animal waste such a big problem in terms of:
Pathogens
Animal waste is a significant problem because it can contain a variety of harmful pathogens that can be transmitted to humans through direct contact, contaminated food, or water, leading to diseases like salmonella.
Why is point source pollution easier to control?
Point source pollution is easier to control than non-point source pollution because it originates from a single, identifiable location, making it easier to pinpoint, monitor, and regulate
What are two ways farmers are trying to use less water?
drip irrigation
What affects your water footprint?
Your water footprint is the amount of water you consume in your daily life, including the water used to grow the food you eat, to produce the energy you use and for all of the products in your daily life – your books, music, house, car, furniture and the clothes you wear.
What is eutrophication?
Why is animal waste such a big problem in terms of:
Chemical contaminants
Animal waste is a significant environmental problem because it contains a variety of chemical contaminants that can pollute water, air, and soil, posing risks to human health and ecosystems.
What are the problems with nonpoint source pollution?
Nonpoint source pollution can include: Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas.
What industry uses up most of our fresh water?
agriculture industry
Why is water footprint a problem?
Many countries have significantly externalised their water footprint, importing water-intensive goods from elsewhere.
What type of chemicals are added to water bodies from pesticides, herbicides and fertilizers?
Nitrogen and phosphorus.
Why is animal waste such a big problem in terms of:
Sedimentation
Animal waste is a significant problem in terms of sedimentation because it can contribute heavily to the buildup of sediment in waterways, which can significantly degrade water quality, harm aquatic life, and even contaminate drinking water sources.
How to stop non-point source pollution?
Limit use of pesticides and fertilizer and use them at appropriate times of the year in recommended amounts.
What is the job of wastewater plants?
Treat used water.
What is the importance of water footprint?
It enables us to determine the magnitude of the impact generated by human activity and obtain objective data.
