    HelloI really enjoy the posts…….thankyou.However there needs to be some more careful editing – especially relating to correct spelling.Recently “manner” was spelled as “manor”, and in this post, “straight” is spelled as “strait”.Spelling matters when meaning is affected!RegardsLexi

    The three main threats to cacti in the wild are development, grazing and over-collection. Development takes many forms. The construction of a dam near Zimapan , Mexico , caused the destruction of a large part of the natural habitat of Echinocactus grusonii . Urban development and highways have destroyed cactus habitats in parts of Mexico, New Mexico and Arizona , including the Sonoran Desert . The conversion of land to agriculture has affected populations of Ariocarpus kotschoubeyanus in Mexico, where dry plains were plowed for maize cultivation, and of Copiapoa and Eulychnia in Chile , where valley slopes were planted with vines.
