1

Around 10,000 BC, at what age did humans evolved in a way of life that was more secure

Neolithic age

2

Early systems might have done this by returning nutrients to the soil

Sustaining Fertility

3

Processes that emphasize efficiency; inorganic synthetic fertilizers are used

Commercial Agriculture

4

The environmental impact of agriculture is?

Multi-faceted

5

Large-scale application of scientific inventions to food production ; goal was to increase production of rice

Green Revolution of Rice

6

The Green Revolution was developed in?

International Rice Research Institute, Los Banos, Laguna

7

Any of a group of genetically enhanced cultivars of crops

High-yielding Varieties

8

First component of technology was the development of HYV's

High Yielding Hybrid

9

Varieties were developed that were?

Shorter with stronger stem and roots

10

Give effects of pesticide to the environment. Air pollution

-pesticide drift occurs when pesticides in the air are carried by wind to other areas
-can volatilize, posing a threat to wildlife
-droplets of sprayed pesticides may travel on wind

11

Produces less pesticide drift than aerial spraying does

Ground spraying

12

Give effects of pesticide to the environment. Water pollution

-may drift outside its intended area when sprayed
-may percolate
-may carried to water as runoff
-may be spilled

13

Give effects of pesticide to the environment. Soil pollution

-decreases the general biodiversity in the soil

14

Give effects of pesticide to the environment. Plants pollution

-pesticides hinder nitrogen fixation, which is required for the growth of the plants

15

The planting of vast areas to only one crop

Monocropping/ Monoculture

16

Produces genetically modified organisms (GMO)

Genetic Engineering

17

Also called transgenic maize corn and is a genetically modified crop

Bt Corn

18

What does BT from BT corn means

Bacillus Thuringiensis

19

Micro organisms found in soil that protects the corn from insects

Bacillus Thuringiensis

20

What is the pest that usually affects corn production

European corn borer

21

A population of what kind of butterfly was affected when pollen of Bt corn was carried by wind

Monarch Butterfly

22

Utilizes species that are locally available and are therefore suited to environmental conditions

Organic farming

23

How does organic farming optimizes the use of biological processes

1. By nurturing the natural predators of pests
2. Keeping the soil healthy with beneficial microorganisms
3. Allowing wild species from nearby natural ecosystems to pollinate crops
4. Encourages variety in space and variety in time through crop rotation
