from the bread basket to a dust bowl?
1. In their greed for new field, the White Americans landowners played havoc with the natural ecology they slashed and burnt forests indiscriminately.
2. The lesson which we have learnt, that in the mad race for growing more and more crops, one should not play havoc with ecology.
3. No trees should be cut and not of leaf of grass should be cut.
4. The ecological balance must be maintained at all cost otherwise everything will turn into a nightmare.
