It helps the environment by when it's winter time instead of the plants to die you can just put them inside of the greenhouse.
It helps the economy by when a person buys a greenhouse they don't have to waste their money on fruits and vegetables.
and a greenhouse helps the society by saving a lot of money. By: Isha Ballgobin How a greenhouse hinders A greenhouse hinders by when we make climate change by emitting less greenhouse gases such as carbon dioxide . The less we emit, the less warming there will be in the future. One of the main problems of a greenhouse One of the main problems about a greenhouse is that it produces greenhouses gases and it wastes a lot of energy, and it also costs a lot of money. Greenhouse effect The components of a greenhouse gardeners, water, buckets, hoses, seeds, plants, soil, heat (furnace), lights, glass, the control system, liquid oxygen tank, fertilizer, natural gas for oxygen generators, liquid oxygen supple mention, carbon dioxide, evaporative pad, ridge vent, gardening accessories, etc. The input of a greenhouse The input of the greenhouse are seeds, money, water, plants etc The output of a greenhouse The output of a greenhouse are plants (vegetables, fruits, flowers, trees), money, resources, food, money (if you sell the product) etc. System The greenhouse is a mechanical, physical, social, and control system. How it can be stop The natural carbon and water cycles support a greenhouse effect in the atmosphere where just enough of the sun's heat is kept back so that life can go on comfortably. Efficiencies Greenhouses do their job most successfully using designs and siting for energy efficiency and maximum light transmission. Greenhouses must optimize crop growth and energy use by allowing sunlight in during the day, retaining as much heat as possible during cold weather, and providing sufficient ventilation to avoid excessive interior temperature and humidity.
Where possible, greenhouse construction materials with the highest insulation values should be used. Proper glazing material decreases energy loss while still allowing the natural spectrum of light inside to facilitate the healthy growth of the plants within. When heating greenhouses, some fuels have a higher heat value than others and some heating units have a greater efficiency. Inefficiencies The inefficiencies are that the greenhouses produce the greenhouse gases Facts Greenhouses have become an important part of the modern agricultural industry as well as for home gardeners. They allow humans to produce food crops out of season and to grow tropical plants and flowers as well as plants for herbal remedies. New technologies are being developed to increase the efficiency and yield of greenhouse production to lessen the dependence on energy. How greenhouse gases has changed overtime Carbon dioxide (CO₂) has increased from our use of fossil fuels which we burn for use in transportation, energy generation, building heating and cooling. Deforestation also releases CO2 and reduces its uptake by plants The Netherlands has some of the largest greenhouses in the world. Such is the scale of food production in the country that in 2000, greenhouses occupied The largest greenhouse in the world.
